1.0 PurposeThe purpose of this Chemical Hygiene Plan (CHP) is to describe laboratory work practices and procedures which are necessary to ensure that University laboratory employees are protected from health hazards associated with many hazardous chemicals used in laboratories. The CHP addresses this objective by including the requirements of the state safety and health regulation, Washington Administrative Code (WAC) 296-828 Safety Standards for Hazardous Chemicals in Laboratories, also known as the Laboratory Safety Standard. This is the primary regulation covering laboratories performing chemical manipulations. In chemical laboratories, this standard supersedes most of the chemical-safety requirements in other regulations.

2.0 ScopeThe Chemical Hygiene Plan applies to all laboratory employees working on laboratory scale operations involving laboratory use of hazardous chemicals. (See Part 3 for definitions of these terms.) The Chemical Hygiene Plan also encompasses non-laboratory personnel required to enter a laboratory where potential exposure may occur. Laboratory personnel are expected to be familiar with their laboratory’s chemical hygiene plan and follow standard operating procedures outlined in the plan.

Any laboratory which meets the definition of a chemical laboratory must complete a Chemical Hygiene Plan for the laboratory by adding laboratory-specific information to this manual. Laboratories which do not meet the definition of a chemical laboratory may refer to this manual for general safety information, but must comply with general industry regulations concerning chemical management.

According to WAC 296-828, a chemical laboratory must also utilize safety practices or safety equipment to reduce the risks of the hazardous chemicals. In addition, the chemical laboratory may not be a production type facility where one process is performed repeatedly to produce a product for others.

3.0 Definitions Action Level: A concentration of a specific substance calculated as an 8-hour time

weighted average (TWA), which initiates certain required activities as designated in WAC 296-62.

Administrative Controls: Operating procedures and policies that serve to reduce the risk of exposure to hazardous materials, such as minimum purchasing and storage, use of alternate materials, and controlled access to materials.

Carcinogen: A carcinogen is any substance or agent that is capable of causing cancer – the abnormal or uncontrolled growth of new cells in any part of the body in humans or animals. Carcinogens are chronic toxins with long latency periods that can cause damage after repeated or long duration exposures and often do not have immediate apparent harmful effects. See also “Select Carcinogen”.

Ceiling Limit: The maximum concentration of a contaminant in breathing air which may not be exceeded for any length of time.

Chemical Hygiene Officer (CHO): An employee qualified by training or experience to provide technical guidance in the development and implementation of the provisions of the Chemical Hygiene Plan. (See Part 4.1)

http://www.lni.wa.gov/safety/rules/chapter/828/WAC296-828.PDF


Chemical Laboratory: A chemical laboratory is defined as an area (which can be a single room, a group of rooms, or a part of a room where chemical manipulations are done for research, educational, or clinical purposes. The manipulations must involve mixing different hazardous chemicals in a variety of formulations, done on a small scale (one person can easily handle the volume of the chemical in use).

Control(s): Equipment, wearing apparel, or prescribed procedures which, when in good working order and properly used, will prevent laboratory employees from being exposed to hazardous materials.

Control Area: Based on the International Fire Code (IFC), a control area is an area that may include a suite of laboratories, one or more floors in a building or an entire building where storage of hazardous materials limits apply. Buildings under newer codes have reduced hazardous material storage quantity limits above the second floor. To assure compliance with the IFC, contact EHS.

Department Safety Coordinator (DSC): An employee who facilitates the flow of health and safety information and programs form EHS into the campus workplace. DSCs work as a liaison between departmental personnel and EHS staff and function as frontline staff in working to achieve safety and regulatory compliance within the department. DSCs are appointed by the department head.

Designated Area: An area which may be used for storage and work with select carcinogens, reproductive toxins, or substances which have a high degree of acute toxicity. A designated area may be an entire laboratory, a section of a laboratory, or a device within a laboratory, such as a fume hood.

Engineering Control: A device or apparatus designated to contain or reduce the risk of hazardous materials. Examples include ventilation, laboratory fume hoods, and shielding. Personal protective equipment such as gloves and face shields are not engineering controls.

Exposure: Physical contact of a person with any material (solid, liquid, or gas) or any form of energy (temperature extreme, electricity, laser, ionizing or non-ionizing radiation, etc.).

Exposure Assessment: The gathering of information by one or more of the following methods for the purpose of estimating the extent of exposure.

o Interview,o Inspection,o Sampling and analysis of air, water, etc.,o Investigation of materials and/or procedures used,o Medical evaluation, ando Other forms of inquiry as deemed appropriate by the Chemical Hygiene Officer.

Hazardous Chemical / Hazardous Substance / Hazardous Energy: A chemical, substance, or form of energy for which there is statistically significant evidence, based on at least one scientific study, that acute or chronic health effects may result from exposure to that chemical, substance or energy. This definition includes substances which present both physical and health hazards.

Health Hazard: Health hazards include chemicals which are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins,

7-6


nephrotoxins, neurotoxins, agents which act on the hematopoietic systems, and agents which damage the lungs, skin, eyes or mucous membranes.

Highly Toxic Chemical: A chemical falling within any of the following categories:

(a) A chemical that has a median lethal dose (LD50) of 50 milligrams or less per kilogram of body weight when administered orally to albino rats weighing between 200 and 300 grams each.

(b) A chemical that has a median lethal dose (LD50) of 200 milligrams or less per kilogram of body weight when administered by continuous contact for 24 hours (or less if death occurs within 24 hours) with the bare skin of albino rabbits weighing between two and three kilograms each.

(c) A chemical that has a median lethal concentration (LC50) in air of 200 parts per million by volume or less of gas or vapor, or 2 milligrams per liter or less of mist, fume, or dust, when administered by continuous inhalation for one hour (or less if death occurs within one hour) to albino rats weighing between 200 and 300 grams each.

Laboratory Personnel: An individual in a laboratory who may be exposed to hazardous chemicals in the course of their assignments.

Laboratory Scale: Work with substances involving containers that can be easily and safely manipulated by one person.

Laboratory Supervisor: An individual who is responsible for setting a standard of behavior and be a safety role model. Provide safety oversight of day-to-day laboratory operations. Incorporate safety discussions in lab group meetings for continuous improvement of best safety practices.

In most research laboratories, the faculty member, principle investigator or research laboratory supervisor is designated as the laboratory supervisor.

In non-research or teaching laboratories, the department head or chair should designate who the laboratory supervisor or responsible party may be.

The responsible party must ensure that the lab has a chemical hygiene plan, chemical inventory is maintained, identify and assess hazards, document and enforce appropriate safety practices, ensure signage and labels are in place, provide and document training, ensure staff have access to safety information such as safety data sheets, and perform accident follow-up.

Lower Flammable Limit (LFL) / Lower Explosive Limit (LEL): The minimum concentration (percent by volume) of flammable vapor in air below which the mixture cannot be ignited.

Permissible Exposure Level (PEL): The maximum concentration of a contaminant in breathing air to which a laboratory worker may be legally exposed, as an 8-hour weighted average.

Physical Hazard: A substance for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric (ignites spontaneously in air), unstable (reactive) or water-reactive. Substances, processes, and forms of energy are also considered to be physical hazards if they involve a potential for skin or eye contact with a hot or cold material, surface, or source of energy sufficient to cause tissue damage or loss of eyesight.

7-7


Principal Investigator (PI): An individual who is required to set a standard for behavior and be a safety role model. In research laboratories, the PI is considered the responsible party. The responsible party must ensure that the lab has a chemical hygiene plan, chemical inventory is maintained, identify and assess hazards, document and enforce appropriate safety practices, ensure signage and labels are in place, provide and document training, ensure staff have access to safety information such as safety data sheets, and perform accident follow-up. The PI has the authority to enforce correct procedures.

Reproductive Toxins: Chemicals that affect the reproductive capabilities, including chromosomal damage (mutations) and effects on fetuses (teratogeneses).

Required Respirator: An appropriate respirator, which is worn to prevent the wearer from breathing a contaminant whose concentration in the air exceeds the PEL. A respirator is required when the air in a work place contains one or more contaminants exceeding a PEL or when sudden failure of an engineering control would create an exposure above the STEL. (Note: Other methods of exposure control take precedence over respirator use. A required respirator is to be used only in situations where other forms of exposure control are not possible. Regulations require that any employee who must work in a respirator be certified by a physician to be physically fit to work in that respirator. This certification must be obtained before the employee can be allowed to work while wearing a respirator, whether supplied by the employer or not.

Select Carcinogen: Any substance that meets one of the following criteria:

o It is regulated by regulations as a carcinogen, or

o It is listed under the category “Known To Be Carcinogens” in the Annual Report on Carcinogens published by the National Toxicology Program (NTP) (latest edition), or

o It is listed under Group 1 (Carcinogenic To Humans) by the International Agency for Research on Cancer Monographs (IARC) (latest edition), or

o It is listed in either Group 2A or 2B by IARC or under the category “Reasonably Anticipated To Be Carcinogens” by NTP, and causes statistically significant tumor incidence in experimental animals in accordance with any of the following criteria:

o After inhalation exposure of 6-7 hours per day, 5 days per week, for a significant portion of a lifetime, to dosages of less than 10 mg/m3,

o After repeated skin application of less than 300 mg/kg of body weight per week, or

o After oral dosages of less than 50 mg/kg of body weight per day.

Short Term Exposure Limit (STEL): The maximum concentration of a contaminant in breathing air to which a laboratory employee may be legally exposed, as a time weighted average, for a maximum (for most contaminants) of 15 minutes.

Well Ventilated Area: An area where the ambient conditions of use include sufficient ventilation to prevent a flammable or combustible vapor/air mixture from reaching the LFL/LEL and the concentration of air contaminants in the breathing zone of laboratory workers from exceeding a PEL.

5.0 Standard Operating Procedures5.1 General Safety Guidelines

Never work alone at a potentially dangerous activity.

When working with flammable materials, be certain there are no sources of ignition near enough to cause a fire or explosion in the event of a spill or vapor release.

Use a shield for protection whenever an explosion or implosion is possible.

The hazardous properties of each material used in a procedure must be determined before the first time it is used. Assume a mixture to be more toxic than any of its components.

7-11


Use proper protective equipment whenever required. Refer to the Department Safety Information Book, Section 5, Personal Protective Equipment.

Know the location and proper use of emergency equipment and be familiar with emergency procedures.

Minimize all chemical exposures; avoid skin contact with chemicals. Immediately notify a Laboratory Supervisor if exposure to a hazardous substance occurs.

Store chemicals in tightly closed containers with readable and accurate labels. (See 7.1 Labeling Hazardous Materials)

Use of hazardous chemicals that may produce gases, fumes, or hazardous vapors must be conducted in a working fume hood. Never use highly toxic agents, carcinogens, or reproductive toxins outside of a working fume hood, unless previously discussed with the Laboratory Supervisor.

Type and scale of work conducted in a laboratory must be appropriate to the physical facilities as well as the quality of the ventilation system.

Be alert to unsafe conditions and report them to the Laboratory Supervisor or the Environmental Health and Safety office for correction.

Visitors to the laboratory are to be escorted by authorized lab personnel and are the responsibility of that individual. All safety regulations must be observed.

5.2 Unattended OperationsAn experiment is considered to be an unattended operation if there is no one immediately present who fully understands the operation and shutdown procedure to be used in the event of an emergency. Reactions that are not well understood should not be permitted to run unattended.

Unattended operations should be prominently labeled with the laboratory employee’s name, start date and time, intended stop date and time, and contact information for the laboratory worker and faculty advisor, if applicable. Leave the laboratory lights on and post warning signs of any associated hazards (e.g. flammable, reactive, explosive, etc.).

Unattended operations that could result in a fire or explosion should be equipped with the necessary automatic shutdown controls.

Use necessary shields or barriers to contain splashes, explosions or other releases.

Establish provisions for containment of toxic substances in the event of a utility service failure, such as loss of cooling water.

5.3 Personal Hygiene Avoid skin contact with chemicals; wash promptly whenever a chemical contacts the skin.

Avoid inhalation of chemicals; do not smell or taste chemicals.

Never pipette by mouth or use mouth suction to start a siphon.

Never bring food, chewing gum, beverages, cigarettes, or food containers into the laboratory. Never eat, drink, smoke, bite fingernails, apply cosmetics, or handle contact lenses while in the laboratory.

Always wash hands with soap and water before leaving the laboratory and before eating, drinking, smoking, using the restroom, applying cosmetics, or handling contact lenses. Areas of exposed skin (such as the forearms) should be washed frequently if there is a potential for contact with chemicals.

Never store food in a refrigerator that is used to store chemicals.

Never use laboratory glassware or utensils for storage, handling, or consumption of food or beverages.

7-12


Ice generated for laboratory use shall not be used for human consumption or food storage.

5.4 Personal Protective Equipment Laboratory workers must always wear appropriate eye protection whenever anyone is

working with hazardous materials or performing hazardous process in the laboratory. Goggles must be worn when there is a potential for splashing or spilling of a hazardous liquid. Face shields should be worn when appropriate.

When working with hazardous chemicals, wear gloves made of a material that is resistant to permeation by that chemical. Latex gloves are typically not permitted for chemical handling. If latex gloves are warranted, potential allergic reactions to latex should be considered prior to use. Disposable nitrile gloves are the minimum hand protection for chemical use. Refer to safety data sheets for proper glove type and make note of permeation data as some chemicals can pass through a protective film without going through pinholes, pores or other visible openings.

Protect skin and feet with adequate clothing and footwear.

Confine loose hair and clothing while working in the laboratory.

The Laboratory Supervisor (or designee) will be responsible for selecting and acquiring appropriate personal protective equipment, maintaining its availability, and establishing cleaning and disposal procedures. Standard personal protective equipment must be provided by the employer to employees free of cost. Student or other non-employee laboratory personnel may be required to purchase personal protective equipment.

Refer to Western Washington University's Safety Information Book, Section 5 (Personal Protective Equipment), Section 13 (Respiratory Protection Program), and Section 14 (Hearing Conservation Program).

Chemical protective clothing must be removed before leaving the work area. Gloves should be removed before touching other surfaces, such as doorknobs, drawer pulls, or faucet handles.

5.5 Clothing Laboratory coats or aprons shall be worn by laboratory personnel whenever handling

liquids that are injurious to or absorbed through the skin.

Laboratory coats must be cleaned regularly. If a spill occurs on the laboratory coat or personal clothing, it must be either decontaminated before reuse or disposed of as hazardous waste.

Laboratory coats must not be laundered with personal laundry.

The commercial firm laundering any contaminated work clothing shall be notified of potentially contaminated substances. Grossly contaminated clothing shall be bagged and disposed of as hazardous waste.

5.6 Housekeeping Lab areas should be kept clean and uncluttered. Spills must be immediately cleaned and

floors must be maintained dry at all times. Contaminated glassware should not be left out.

Access to exits, emergency equipment, eyewashes, safety showers, fire extinguishers, emergency spill equipment, circuit breakers, and fire alarm pull boxes must never be blocked.

7-13


All chemical containers must be labeled with (at least) the identity and hazards of its contents.

Waste must be properly labeled and kept in proper containers. (See Section 14 – Waste Disposal Procedures)

Chemicals should be stored in an earthquake-safe storage area and should be returned to their storage area after use.

5.7 Operations Requiring Prior ApprovalThe following laboratory operations require prior approval from the department head, department safety coordinator, or laboratory supervisor.

Newly developed high hazard experiments or processes

Procedures for which the laboratory worker has not been trained

Operations or activities for which there are no written procedures,

Completing a medical examination prior to respirator use when performing procedures

involving certain hazardous substances

Work with unknown substances,

Work in designated areas.

5.8 Planning Chemical Laboratory Experiments Consider all possible reactions, including side-reactions, before beginning.

Think through all reactants, intermediates, and products in terms of flammability, toxicity, route of entry, and reactivity hazards.

Follow recognized safe practices concerning personal protective equipment, housekeeping, and handling of hazardous chemicals as outlined in this chemical hygiene plan.

When conducting unknown reactions, always start with small quantities of material and carefully observe reaction characteristics before increasing quantities.

Obtain safety information about reactants and by-products.

If possible, determine the quantity and rate of evolution of heat and gases to be released during the reaction.

Provide adequate cooling, ventilation, pressure relief, and gas purging. If possible, isolate the reaction vessel and make frequent inspections of equipment during the reaction. Do not leave a hazardous system unattended.

Consider the recommended first aid treatment for each reactant, intermediate, and products.

Develop a plan of action for situations such as power failure, cooling system failure, exposure of the system to water or air, unexpected increase in pressure, or broken reaction containers.

5.9 Emergency ProceduresRefer to Western Washington University Safety Information Book, Section 2 (Emergency Chemical Procedures) for information on emergency procedures and the Departmental Emergency Plan.

5.10 Accidents and Accident Reporting

7-14


Accidents or injuries that occur in the laboratory and require medical treatment must be reported immediately and treated immediately. Personnel trained in first aid and CPR must be available during working hours to render assistance until medical help can be obtained.

All accidents, whether resulting in injury or damage, should be carefully analyzed with the results reported to all who might benefit. Accident reports will be kept on file with the Director of Environmental Health and Safety and will be made available to personnel upon request. Please refer to Western Washington University Safety Information Book, Section 4 (General Safety Information Accident Prevention Plan) for more information on accident reporting.

6.0 Chemical Procurement, Distribution, and Storage6.1 Chemical Procurement and Distribution

The Department Safety Coordinator reviews the purchase of all new hazardous chemicals. Prior to purchase of new hazardous chemicals, the following must be considered:

o Proper storage, handling, and disposal procedures,

o Facility requirements for safe handling of the material, and

o Personnel training or proficiency necessary for safe handling of the material.

Before a substance is received, information of proper handling, storage, and disposal should be known. All Safety Data Sheets (SDSs) received with shipments to a laboratory will be maintained in the department either electronically or via paper method. Please refer to Western Washington University Safety Information Book ,Section 6 (Hazard Communication) for more information on SDS Management.

No container will be accepted without an adequate identifying label. This label should include the substance name, an appropriate hazard warning, and specific target organ effects.

6.2 Chemical Inventory The chemical inventory is kept in the department. Refer to Western Washington

University Safety Information Book, Section 6 (Hazard Communication) as it provides the inventory or its location.

Physical inventories are conducted annually to identify leaking or damaged containers, containers with missing or illegible labels, and chemicals that are no longer needed.

6.3 Chemical Distribution When chemicals are hand-carried, they are placed in a secondary container to protect

against breakage and spilling.

Large compressed gas cylinders are transported with a suitable handcart and strapped in place during transport.

6.4 Chemical Storage PracticesEstablish and follow safe chemical storage and segregation procedures for your laboratory. Practices will include:

Provide an appropriate storage place (following guidelines in Appendix 7B, Table 7-2) for each chemical and return the chemical to that location after use.

Storage and working amounts of hazardous chemicals are kept to a minimum.

Chemical storage in fume hoods is kept to a minimum.

7-15


Chemicals are stored in containers with which they are compatible; containers are kept closed when reagents are not being used.

All chemical containers must have a legible, firmly attached label. The containers are dated when received and when opened.

Keep peroxide forming chemical containers tightly closed and away from light sources. Containers should also be opaque. Label container with the date received and date opened. Test for peroxides regularly, preferably before each use. Record the test data on the label for the next user. If the concentration exceeds 10 ppm, contact your department safety coordinator, immediate supervisor or EHS at x3064. (See 7.1 Labeling Hazardous Materials and 16.3.1 Reactive Chemicals and Appendix 7B, Table 7-5)

Compressed gas cylinders are individually secured at all times; cylinder caps must be in place on cylinders when not in use.

Incompatible chemicals must be segregated. See Appendix 7C, Table 7-2 for a partial list of incompatible chemicals.

Chemicals are stored on shelves or in cabinets that prevent the containers from falling in the event of an earthquake. Heavy items and corrosive materials are stored on shelves near the floor.

Avoid storing chemicals on bench tops

Avoid storing chemicals in laboratory hoods

Containers of chemicals must be capped when not in use; make sure that caps on containers are secure; replace damaged caps.

Chemicals should not be stored under the sink, near the sink or in the sink, to minimize the chance of accidents and improper discharges to the sanitary sewer. Any vapors of corrosive materials and bases will cause corrosion of the plumbing fixtures under the sink. Some chemicals, including many corrosives, are water reactive and, in the event of a water leak, there can be unanticipated and unfortunate consequences.

Do not store chemicals in hallways, corridors or exit ways.

Use secondary containment to prevent incompatible chemicals from mixing and reacting with each other if they must be stored adjacent to each other on a benchtop.

Maintain the lowest possible quantities of highly toxic chemicals

Chemicals with a high degree of toxicity (e.g. venoms, mycotoxins, and select agents) should be doubly contained and stored in a locked area accessible only by authorized personnel.

If containers are placed on refrigerator/freezer door shelves, use secondary containers, additional barriers, Velcro or other protective measures to keep them from falling out when the door is opened.

Use secondary containment or spill control, such as placing the container on an absorbent pad (generally required for containers on the floor).

6.5 Spill Response

7-16


Locations where chemicals are stored should have available a supply of equipment and materials for use in the event of a chemical spill. Spill response materials may include:

Absorbent Personal protective equipment Scoops and/or pans for picking up granular solids Plastic bags to contain contaminated absorbent

For spills creating an airborne hazard or that require equipment beyond standard laboratory apparel, contact the Environmental Health and Safety office for assistance in containment and clean up.

7.0 Hazard Identification All chemical containers must have a legible, firmly attached label showing the contents of

the container.

Labels on incoming containers of hazardous chemicals must not be removed or defaced.

Safety Data Sheets (SDSs) received with incoming shipments of hazardous chemicals are maintained and made readily accessible to laboratory personnel. SDSs are kept in the department. Refer to Western Washington University Safety Information Book, Section 6 (Hazard Communication) for information on SDS locations.

A hazard review of new materials not previously used in the laboratory shall be completed before working with the new material. The Department Safety Coordinator or Laboratory Supervisor conducts this review. (See Part 6.1 – Chemical Procurement and Distribution)

Chemical substances developed in the laboratory are assumed to be hazardous in the absence of other information.

Laboratory areas that have special or unusual hazards should be identified with an appropriate warning sign.

7.1 Labeling Hazardous Materials

1. Original Container

The label on an original container must be legible and written in English. It must include the chemical/ product name as shown on the safety data sheet (SDS) and the manufacturer’s name and address. Do not accept materials if the label is illegible or missing required information.

Beginning June 1, 2015, labels on chemicals and products shipped from the manufacturer must be consistent with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) as required by Washington Administrative Code (WAC) 296-901. There are six required WAC elements as of June 1, 2015:

1. Product name 2. Manufacturer’s name and contact information 3. Signal word (e.g., danger, warning or no signal word) 4. Hazard statement(s) (e.g., toxic if inhaled, combustible liquid) 5. Pictogram(s) 6. Precautionary Statements (e.g., keep container tightly closed)

7-17


Figure 7-1, Example of Original Label

Avoid damaging the original container’s label, if possible. If a container label becomes illegible, replace the label. The replacement label must include the six required WAC elements to be in compliance with GHS rules, Contact EHS at 360-650-3064 or [email protected] for assistance.

2. Labeling Stock/ Working Solutions

Containers of preparations, sample aliquots, and other working solutions are not required to be labeled if the container will be emptied before the end of the work shift and used by only one person. If a preparation or working solution is kept for a longer period than day of use or be used by others, the container must be labeled with the following information:

Identity of the contents (spell out chemical names) Signal word, if known or suspected (e.g., danger, warning) Hazards, if known or suspected (e.g., flammable, corrosive, irritant)

It is also “best practice” to label the working solution with the initials of the person preparing the solution and the date of preparation. Information about the signal word, the hazards, and the precautionary statements from the label, can be obtained from the SDS, but dilutions and reactions may change the hazards and their severity. See Table 7-1 below for examples of physical and health hazards.

a. Labeling Specialized Containers

Containers that are too small for labels, installed into a process, or would become unusable for their intended purpose if labeled, must still have their contents identified in some way. Use any labeling method that enables personnel and visitors from other agencies, such as the fire department, to identify the chemicals and their hazards. Examples include a sign identifying the materials and their hazards, color or numeric codes cross-referenced on a chart, or room diagrams identifying locations of the chemicals and hazards.

b. Additional Label Required for Peroxide-Forming Chemicals

Label chemicals that form peroxides with the date the container was first opened. This will assist in conducting tests for peroxides at an appropriate frequency as noted in the University and each department’s Chemical Hygiene Plan.

c. Labeling Waste Containers

Waste containers must be labeled following guidelines in Section 10 Hazardous Waste Program of the Safety Information Book. If re-using a container to hold waste, the container must be compatible and appropriate for the waste. Completely deface all old labels on containers used for wastes.

For radioactive and biological waste, please contact your department safety coordinator or EHS at x3064.

8.0 Environmental MonitoringEmployee exposure to regulated substances shall not routinely exceed the action level or, in the absence of an action level, the PEL. When there is reason to believe that employee exposure levels of regulated substances are routinely exceeding the action levels, employee exposure to these substances will be monitored.

In the event that the action level is exceeded, Western Washington University will immediately comply with the exposure monitoring requirements of the standard for that substance (WAC 296-62). In addition, environmental monitoring of airborne concentrations of hazardous chemicals should be conducted in the following conditions:

When requested by a laboratory employee or a concerned party as a result of a documented health concern or suspicion that a PEL is being exceeded,

7-19


When a highly toxic substance is being regularly and continuously used outside of a chemical fume hood (three or more times a week)

The Environmental Health and Safety office will ensure that employee exposure is monitored. Exposure testing procedures and monitoring results are provided to the Department Head, Laboratory Supervisor, and personnel within 15 working days after receipt of the results. An accurate record of all measurements taken to monitor employee exposures will be kept, transferred, and made available for each employee in accordance with Provide access to employee medical records, exposure records and analyses requirement (WAC 296-802-40005).

13.2 Reference MaterialsReference materials on the hazards, safe handling, storage, and disposal of hazardous chemicals can be found in many location(s). Contact the Environmental Health and Safety office or refer to their website at http://www.wwu.edu/ehs/ for links.

14.0 Waste Disposal ProceduresChemical waste disposal procedures can be found in Western Washington University Safety Information Book, Section 10 (Hazardous Waste Program).

15.0 Ventilation15.1 General Guidelines

General laboratory ventilation shall provide airflow into the laboratory from non-laboratory areas and out to the exterior of the building.

All operations that might result in the release of unpleasant and/or potentially hazardous fumes, vapors, gases or dust must be conducted with local exhaust ventilation.

Storage in a fume hood is kept to a minimum, should not include flammable chemicals, and should not restrict ventilation or airflow.

15.2 InspectionsLaboratory employees should check fume hoods to ensure proper working order before each use. This should include a visual inspection of the hood area for storage or other visible blockages.

Further information on chemical fume hoods can be found in Western Washington University Safety Information Book, Section 8 (University Chemical Fume Hood Program).

16.0 Chemical Handling ProceduresRefer to Appendix 7B, Table 7-2 for information on proper storage for flammables, corrosives, and reactive chemicals.

16.1 Flammable Liquids and Solids16.1.1 Hazards

Flammable vapors can form ignitable mixtures in air. Vapors can travel great distances and be ignited by remote ignition sources, flashing back violently to the source.

Many flammable liquids are toxic by inhalation and/or skin contact.

7-24

http://www.wwu.edu/ehs/


Flammable liquids or their vapors can cause eye injury, ranging from irritation to severe damage.

16.1.3 Controls Perform work with flammable liquids in a properly functioning chemical fume hood

whenever possible.

Clean up spills of flammable materials immediately.

16.2 Corrosive Chemicals16.2.1 Hazards

Contact with the skin, eyes, respiratory system, or digestive tract can cause severe irritation and burns.

16.2.2 Controls Use appropriate personal protective equipment when handling corrosives. Safety

goggles are required for liquid corrosives.

In case of contact, flush the affected area with large amounts of water for at least 15 minutes, remove contaminated clothing, and seek medical attention.

Always add acid to water when diluting.

16.3 Reactive Chemicals16.3.1 HazardsReactive chemicals are those which:

Are oxidizers (can initiate or support combustions),

Are organic peroxides (can form shock-sensitive explosives upon prolonged storage),

Are explosive,

Can react with other materials (including water) to release hazardous gases or can react violently or with the generation of large amounts of heat, or

Can polymerize violently with the release of large amounts of heat.

16.3.2 Controls Use appropriate personal protective equipment when handling reactive chemicals.

Read and understand handling instructions provided by the precautionary label or SDS.

Perform work with reactive chemicals in a properly functioning chemical fume hood whenever possible.

Perform potentially violent reactions behind a barrier or shield, or at a sufficient distance from any laboratory personnel.

16.4 Compressed Gases16.4.1 Hazards

Compressed gases contain large amounts of energy that can cause serious injury and physical damage. Compressed gases may also be flammable, toxic, or corrosive.

16.4.2 Storage The cylinder must be in good condition with an operable valve. Cylinders not in use

should be capped.

Compressed gases must be stored in the upright position firmly secured with straps, chains or stands designed for this purpose. There are three exceptions:

7-25


o Containers designed for use in the horizontal position

o Compressed gas containers with a water volume less than 5 liters are allowed to be stored in the horizontal position

o Compressed gas containers containing liquefied gases.

Compressed gas cylinders should be stored in an organized, ventilated, well-lit place away from incompatible materials.

Do not remove or damage manufacturer applied labels, decals, or cylinder content information. If the label is no longer legible, contact the vendor for pickup or contact EHS for more information.

Storage outside should be above grade, dry and protected from weather extremes. Avoid direct contact with soil or non-paved surfaces.

16.4.3 Controls Transport compressed gas cylinders with caps in place, secured to suitable containers.

Each cylinder must be matched with the appropriate fitting and regulator. Using regulator-adaptors is prohibited.

Use only commercially manufactured regulators suitable for type of gas and cylinder you are using.

Regulators must be fitted with check valves to prevent inadvertent mixing of gases and suck-back into the cylinder.

Cylinder valves should always be opened slowly; do not stand in front of regulators when “cracking open” cylinder valves.

Avoid completely emptying cylinders. Leave residual pressure in the cylinder and mark it as “empty”.

16.4.4 Transportation and Elevators

Always cap a cylinder before you move it. Cylinders must always be transported using a hand truck or cart designed for that purpose. Safety glasses and closed toe shoes should be worn when handling cylinders.

When moving compressed gas cylinders:

1. Have the metal outlet cap/plug installed,2. Have the valve cap installed if the cylinder has one, and3. Secure cylinders in a cart or container designed to prevent the cylinder from falling

over while being moved.4. Use service or freight elevators.

Additional requirements for compressed gasses and cryogens:

1. Transport compressed gasses and cryogens (for example, liquid nitrogen) using one of the following methods:

a. Exclude people from the elevator by posting a sign on the cart carrying the cylinder. The sign should read Do Not Enter. Compressed Gas Transport. Ideally, someone sends the elevator up and another person waits on the receiving floor to take the cryogens out of the elevator. If

7-26


this is not possible then another plan should be devised to ensure that the cryogen is taken out of the elevator once it reaches the needed floor.

16.5 Carcinogens, Mutagens, Teratogens, and Reproductive Toxins16.5.1 HazardsExposure can induce carcinogenesis, mutagenesis (chromosomal damage), teratogenesis (fetal damage), and infertility. Exposure may affect future generations.

16.5.2 Controls Work with these chemicals only in designated areas. (See Part 17.1 – Use of Designated

Areas)

Wear appropriate personal protective equipment. Avoid skin contact and always wash hands and arms immediately after working with these chemicals.

Work only with adequate engineering controls such as glove bags, glove boxes, and fume hoods.

Laboratory employees should be familiar with emergency procedures for accidents or spills involving these chemicals. The department safety coordinator or designee should be notified of all incidents of exposure or spills.

The Laboratory Supervisor should keep records of the amounts of these materials used and the names of workers involved.

16.5.3 Examples of Carcinogens, Mutagens, Teratogens, and Reproductive ToxinsExamples of these chemicals are listed in Appendix 7B, Tables 7-3 and 7-7, 8, and 9. Additional information can be found on the International Agency for Research on Cancer (IARC) and National Toxicology Program websites.

16.6 Toxic Metals16.6.1 HazardsThese chemicals are toxic by inhalation, ingestion, and possibly by skin absorption.

16.6.2 Controls Wear appropriate personal protective equipment when handling toxic metals.

Work in a fume hood whenever possible.

Spills should be immediately cleaned up and the work area properly decontaminated.

16.6.3 Examples of Toxic MetalsExamples of toxic metals are listed in Appendix 7B, Table 7-10.

16.7 RadionuclidesThe Radiation Safety Officer and State of Washington have strict policies and procedures for the procurement, handling, use, and disposal of radioactive materials. These procedures must be followed by anyone using radionuclides. Contact the Environmental Health & Safety Department for further information.

17.0 Substances of Moderate to High Chronic Toxicity or High Acute Toxicity (Including Select Carcinogens)

17.1 Use of Designated AreasA “designated area” must be established and clearly marked for storage and work with “Select Carcinogens”, reproductive toxins, and substances that have a high degree of acute toxicity. This

7-27

http://monographs.iarc.fr/ENG/Classification/


area may be an entire laboratory, a section of a laboratory, or a device within a laboratory, such as a fume hood or balance. See Appendix 7C for a table of designated areas within the department.

17.2 Controls The Department Safety Coordinator reviews the use and disposal of these substances.

Use properly functioning control equipment (fume hood, glove box, etc.) for procedures that may result in the generation of aerosols or vapors containing the substance. Released vapors should be trapped to prevent their discharge with the hood exhaust.

Protect vacuum pumps from contamination by traps or other devices. Decontaminate vacuums pumps and other contaminated equipment before removing them from the designated area.

Weigh materials only in closed containers unless balances are included in designated areas. Open containers to add or remove chemical in ventilated areas.

Wear appropriate personal protective equipment. Avoid skin contact and always wash hands, arms, face, and neck immediately after working with these chemicals.

The Laboratory Supervisor maintains records of the amounts of these materials on hand, amounts and dates used, and names of laboratory employees involved.

Laboratory employees should be familiar with emergency procedures for accidents or spills involving these chemicals. The Department Safety Coordinator should be notified of all incidents of exposure or spills. If a major spill occurs outside of the fume hood or glove box, emergency responders should wear appropriate personal protective equipment and all other workers should evacuate the area.

Do not work alone when using compounds of high or unknown toxicity.

Contaminated clothing should be chemically decontaminated or destroyed.

Determine the appropriateness of medical surveillance for employees if they are working with toxicologically significant quantities of these substances on a regular basis.

Appendix 7B – Chemical InformationTable 7-2 – Chemical Storage Recommendations

Flammables Store in approved safety cans or cabinets. Do not store incompatible materials in the same cabinet. Keep away from any source of ignition: heat, sparks, or open flames. Flammable solids must be segregated from flammable liquids

Acids Do not store with flammable solvents or combustibles. Ideally, store in a cabinet designed for acids; do not store acids on metal shelving. Segregate inorganic from organic acids. Isolate nitric acid and perchloric acid from everything; including other perchlorics.

Bases Store in corrosives cabinet or on protected shelving away from acids. Segregate inorganic from organic bases.

Light-Sensitive Chemicals

Store in amber bottles in a cool, dry, dark place.

Nitrated compounds Nitrated compounds can be considered explosive; special care and handling may be required

Oxidizers Store in a cool, dry place away from flammables and reducing agents. Oxidizers must not be stored on wooden shelves or in cardboard boxes.

Peroxidizable Chemicals

Store in airtight containers in a dark, cool place. Most peroxidizable compounds are flammable and should be stored in a flammable liquid storage cabinet or room. Label containers with receiving and opening dates. Test for the presence of peroxides at least every six months. Discard before exceeding expiration date. Inspect peroxide forming chemicals often for evidence of contamination, degradation, or any change from normal physical or chemical characteristics. If you suspect a material may have become explosive, contact EHS immediately and post “warning sign” so others do not handle or disturb the material.

Pyrophoric Substances

Store in a cool, dry place, making provisions for an airtight seal. Materials (e.g., tert-butyl lithium) will react with the air to ignite when exposed

Toxic Chemicals Store according to the nature of the chemical, using appropriate security where necessary. Generally, store in a ventilated, dry, cool area in a chemically- resistant secondary container

Water-Reactive Chemicals

Store in a cool, dry location away from any water source, including sprinkler systems. Have a Class D fire extinguisher available in case of fire

Compressed Gas Containers

Store in a cool, dry place, preferably outside of the building and secured with a chain. Separate flammables and oxidizers by 20 feet or a 1-hour rated firewall.
